The FARIA MG2000 Tachometer
combines the features of an ECU serial
bus gateway and several instruments
into one unit:
• The tachometer is analog in
appearance but driven by a stepper
motor for digital accuracy.
• The high resolution LCD screen
displays information for many other
functions and the various “screens”
can be configured as the user
wishes. As received, the screens
are configured as shown in Fig. 1.
The MG2000 receives digital engine data
from the Engine Control Unit (ECU) via
the GM ALDL bus and can receive GPS
information via a NMEA 0183 connection
to a suitable GPS unit. GPS information
is displayed in the MG2000 speedometer.
Analog inputs are provided for two non-
engine sensors such as fuel level and oil
pressure.
The MG2000 provides a Faria Bus output
to allow use of various other 5, 4, and 2
inch instruments with the MG2000.
The Faria MG2000 Tachometer will turn
on when the ignition key is turned on and
will turn off when the ignition key is turned
off. The unit will power up showing the
default screen selected by the user.
Default Screens
Figure 1
The instrument has three push buttons;
“M” “Mode”, “Down”, and “Up”; that
control the functions available. The “M”
“Mode” button is used to change the
function of the LCD display and to access
submenus and adjustable settings. The
“Down” and “Up” buttons are used to
modify the settings.
In the “Normal” operation mode, pressing
the “Mode” button and then pressing
“Down” or “Up” button causes the display
to cycle between the available screens
Page 1
(see Figure 2). Press the “Mode” button
to exit the “screen selection mode” and
return to “Normal” mode or do not push
any buttons for 4 seconds and the current
screen will stay selected and the unit will
return to “Normal” mode (see Figure 3).
In the “Normal” operation mode, press
the “Mode” and “Up” buttons to change to
the “Edit” menus (see Figure 3 and “Edit”
mode below).
Press the “Down” or “Up” buttons to cycle
between the available “Edit” functions.
Press and hold the “Down” and “Up”
buttons for two (2) secs to select an
“Edit” function to change. Within each
“Editing” function the “Down” or “Up”
buttons select settings or sub-functions.
Follow the instructions in the “Edit” mode
section of this manual to save the new
settings after you select / adjust them.
To exit the “Edit” mode after the edit is
completed, press the “Mode” button to
return to “Normal” mode.
Normal Mode
When the MG2000 is turned on the unit
will “beep” once, flash once and then the
unit enters “Self Test” mode. The screen
will display “The Self Test Mode Is In
Operation” for 10 seconds.
The horn will sound three times and the
warning lights and back lights will flash
three times. When this is complete, the
software ID and revision screen will show
for two seconds, then the user selected
“Default” screen will appear.
Contrast and Lighting
In the “Normal“ operating mode the
instrument display contrast and display
mode can be adjusted by pressing the
“Down” and “Up” buttons.
With the display in “Positive” mode, black
on white, pressing the “Down” button
decreases the contrast. Pressing the
“Up” button increases contrast.
Continuing to press the “Up” button
causes the display to reverse to the
“Negative” mode, white on black. The
contrast in this mode is controlled the
same way as the “Positive” mode.
To return to “Positive” mode, continue to
press the “Down” button until the display
reverses.
Page 2
To adjust the lighting intensity of all of
the instruments in the system, press and
hold both the “Down” and “Up” buttons
for 2 seconds. The lighting intensity may
now be adjusted by using the “Down” or
“Up” buttons.
Return to the “Normal” mode by pressing
and holding both the “Down” and “Up”
buttons for 2 seconds.
Displayed Functions
Tachometer
The tachometer is a digital instrument with
the appearance of an analog instrument.
The tachometer receives data directly
from the ECU so no settings are required
for the dial range. A microprocessor
controlled stepper motor moves the
pointer to display engine revolutions per
minute.
Default Screen “1”
Volts
Displays system voltage as received
from the ECU (Engine Control Unit).
OIL PRESSURE
Analog input. Displays information from
the analog oil pressure sender.
Default Screen “2”
Fuel Left
Displays the quantity of fuel remaining
in the fuel tank based on the original
quantity of fuel in the tank when full and
the amount of fuel used based on the
GPH from the engine ECU and the time
spent at each GPH. Fuel tank size and
reset are available in the “Edit” mode.
Fuel Used
Displays the amount of fuel used since
reset based on the GPH from the engine
ECU and the time spent at each GPH.

or “Engine Emergency Stop !”.
Accessing the “View“ mode when the
Alarm screen appears will allow more
information to be displayed about the
alarm if provided by the engine.
